We already know about Microsoft's impending Windows 8 overhaul, but previews of app specific updates have been few and far between. Now, thanks to an apparent Windows Store update on leaked builds, we're starting to see what kind of updates we can expect. In addition to updates for the news, weather, travel, finance and sports apps (see the video after the break), images are leaking for the OS' new calculator application, sound recorder, Movie Moments and an Xbox Music redesign. It's hard to judge these tweaks without actually handling the update ourselves, but we'll say it again for good measure: we may have to review Windows 8all over again.
